Description

Die Erfindung betrifft ein Verfahren zur Druckvorbereitung eines Druckwerks, das mindestens ein Farbwerk mit einer mit einer Rakel zusammenwirkenden Rasterwalze umfaßt, die mit einem mit farbführenden Näpfchen versehenen, auswechselbaren Rastermantel belegbar, die mit Formzylinderdrehzahl angetrieben und deren Durchmesser in betriebsbereitem Zustand gleich dem Druchmesser des mit einer Druckform belegten Formzylinders ist sowie ein zur Durchführung des Verfahrens geeignetes Druckwerk.The invention relates to a method for printing preparation of a printing unit, which comprises at least one inking unit with an anilox roller interacting with a doctor blade, which can be coated with an interchangeable raster jacket provided with ink-guiding cups, which is driven by the forme cylinder speed and whose diameter in the operational state is equal to the diameter of the a printing form occupied by a forme cylinder and a printing unit suitable for carrying out the method.

Aus der DE-OS 37 06 011 ist ein Farbwerk mit einer Rasterwalze bekannt, deren Näpfchen in einer kompressiblen Trägerschicht, die auch als auswechselbare Platte ausgebildet sein kann, angeordnet sind. Durch Änderung des Anpreßdrucks der Rakel wird das Volumen der Näpfchen und damit die Menge der dem Plattenzylinder zugeführten Farbe geändert. Eine Änderung der übertragenen Farbmenge zwischen bestimmten Bereichen der Rasterplatte ist jedoch nicht vorgesehen. Außerdem unterliegt die Anordnung wegen der Anstellung der Rakel an eine nachgiebige Schicht einem verhältnismäßig hohen Verschleiß.From DE-OS 37 06 011 an inking unit with an anilox roller is known, the cells of which are arranged in a compressible carrier layer, which can also be designed as an exchangeable plate. By changing the contact pressure of the doctor blade, the volume of the cells and thus the amount of ink supplied to the plate cylinder are changed. A change in the amount of color transferred between certain areas of the grid plate is not provided. In addition, the arrangement is subject to a relatively high level of wear due to the fact that the doctor blade is positioned against a flexible layer.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine zu seiner Durchführung geeignete Vorrichtung zu schaffen, mit dem eine exakte Dosierung der dem Formzylinder zuzuführenden Farbe, sowohl in Umfangsrichtung als auch in Längsrichtung der Rasterwalze bei geringem Verschleiß der Teile ermöglicht wird.The invention has for its object to provide a method and a device suitable for its implementation, with an exact dosage of the ink to be supplied to the forme cylinder, both in the circumferential direction and in the longitudinal direction of the anilox roller with little wear of the parts is made possible.

Das zur Durchführung des erfindungsgemäßen Verfahrens geeignete Offsetdruckwerk nach Fig. 1 umfaßt einen Gummituchzylinder 1 und einen Formzylinder 2, auf den eine für den Offsetdruck geeignete Druckform 3 aufgespannt ist. Der Formzylinder 2 wirkt mit einer Farbauftragwalze 4 zusammen, die eine nachgiebige farbannehmende Oberfläche aufweist. Der Farbauftragwalze 4 wird die Farbe von einer Rasterwalze 5 zugeführt. Auf die Rasterwalze 5 ist ein als Rasterplatte ausgebildeter Rastermantel 6 aufgespannt. Der Durchmesser der mit dem Rastermantel 6 belegten Rasterwalze 5 ist gleich dem Durchmesser des betriebsbereiten Formzylinders 2. Der Formzylinder 2 und die Walzen 4, 5 werden mit gleicher Drehzahl angetrieben. Auch die Farbauftragwalze 4 weist den gleichen Durchmesser auf. Die den Rastermantel 6 bildende Platte besteht aus einem harten Material mit einer ebenen Oberfläche, in die Näpfchen eingebracht werden. Beim dargestellten Ausführungsbeispiel findet als Rastermantel 6 eine Tiefdruckwickelplatte Verwendung, wie sie im einzelnen in den Figuren 3 und 5 dargestellt ist. An die Rasterwalze ist eine Kammerrakel 7 angestellt, mit der gleichzeitig Farbe zur Rasterwalze 6 geführt und anschließend deren Oberfläche abgerakelt wird. Weiterhin ist ein nur schematisch angedeutetes Feuchtwerk 8 beliebiger Bauart vorgesehen, mit dem Feuchtmittel auf den Formzylinder 2 aufgetragen werden kann. Letztlich ist ein Gegendruckzylinder 9 vorgesehen, mit dem eine Bedruckstoffbahn 10 an den Gummituchzylinder 1 angedrückt wird. Der Gegendruckzylinder 9 kann dabei der Gummituchzylinder eines weiteren Druckwerkes sein.1 comprises a blanket cylinder 1 and a forme cylinder 2, onto which a printing form 3 suitable for offset printing is clamped. The forme cylinder 2 interacts with an inking roller 4, which has a resilient ink-accepting surface. The ink is applied to the inking roller 4 by an anilox roller 5. A screen jacket 6, designed as a screen plate, is clamped onto the screen roller 5. The diameter of the screen roller 5 covered with the screen jacket 6 is equal to the diameter of the ready-to-use forme cylinder 2. The forme cylinder 2 and the rollers 4, 5 are driven at the same speed. The inking roller 4 also has the same diameter. The plate forming the grid jacket 6 is made of a hard material with a flat surface into which wells are introduced. In the exemplary embodiment shown, an intaglio wrapping plate, as shown in detail in FIGS. 3 and 5, is used as the grid jacket 6. A chambered doctor blade 7 is placed on the anilox roller, with which ink is simultaneously fed to the anilox roller 6 and then its surface is doctored off becomes. Furthermore, a dampening unit 8 of any type, indicated only schematically, is provided, with which dampening solution can be applied to the forme cylinder 2. Ultimately, an impression cylinder 9 is provided with which a printing material web 10 is pressed onto the blanket cylinder 1. The impression cylinder 9 can be the blanket cylinder of another printing unit.

Fig. 2 läßt erkennen, daß die Druckform 3 mehrere druckende Bereiche 11, 12, 13 aufweist, zwischen denen nichtdruckende Bereiche verbleiben. Wenn mit der Druckform nach Fig. 2 gedruckt werden soll, wird ein Rastermantel 6 nach Fig. 3 hergestellt, der mit farbaufnehmenden Bereichen 14, 15, 16 versehen wird, zwischen denen farbabstoßende Bereiche liegen.Fig. 2 shows that the printing form 3 has a plurality of printing areas 11, 12, 13, between which non-printing areas remain. If the printing form according to FIG. 2 is to be used for printing, a grid jacket 6 according to FIG. 3 is produced, which is provided with ink-receiving areas 14, 15, 16, between which ink-repellent areas lie.

Anschließend werden die Druckform 3 und der Rastermantel 6 auf den Formzylinder 2 bzw. die Rasterwalze 5 aufgespannt. Die Aufspannung des Rastermantels 6 erfolgt dabei so, daß die vom Bereich 14 aufgenommene Farbe über die Farbauftragwalze 4 zum druckenden Bereich 11 der Druckform 3 weitergeleitet wird. In gleicher Weise wird die von den Bereichen 15, 16 aufgenommene Farbe über die Farbauftragwalze 4 zu den Bereichen 12, 13 der Druckform 3 geführt.The printing form 3 and the grid jacket 6 are then clamped onto the forme cylinder 2 or the screen roller 5. The grid jacket 6 is clamped in such a way that the ink picked up by the area 14 is passed on via the inking roller 4 to the printing area 11 of the printing form 3. In the same way, the ink picked up by the areas 15, 16 is guided via the inking roller 4 to the areas 12, 13 of the printing form 3.

Die farbaufnehmenden Bereiche der Rastermantels 6 werden dabei, wie Fig. 5 zeigt, durch Näpfchen 17 gebildet, die in eine Photopolymerschicht 18 eingebracht werden. Die Photopolymerschicht 18 ist fest mit einer Trägerschicht 19 verbunden.As shown in FIG. 5, the ink-receiving areas of the grid jacket 6 are formed by cells 17 which are introduced into a photopolymer layer 18. The photopolymer layer 18 is firmly connected to a carrier layer 19.

Durch diese Maßnahmen wird erreicht, daß der Rastermantel 6 nur in den Bereichen Farbe aufnimmt und weiterleitet, in denen tatsächlich ein Farbbedarf der Druckplatte vorliegt.These measures ensure that the grid jacket 6 receives and transmits ink only in the areas where there is actually a color requirement of the printing plate.

Während bei dem Rastermantel 6 gemäß Fig. 3 in den Bereichen 14 bis 16 eine gleichmäßige Näpfchenverteilung vorgesehen ist, erfolgt bei dem Rastermantel 20 gemäß Fig. 4 eine noch exaktere Farbdosierung. Hierzu ist das zu druckende Sujet der Druckform 3 auf denWhile in the areas 14 to 16 a uniform cell distribution is provided in the grid jacket 6 according to FIG. 3, an even more precise color metering takes place in the grid jacket 20 according to FIG. 4. For this purpose, the subject of printing form 3 to be printed is on the

Rastermantel 20 in allen Einzelheiten aufgebracht. Infolgedessen führt jedes farbführende Näpfchen des Rastermantels 20 ein Farbpartikel über die Farbauftragwalze 4 zu einer Stelle der Druckform 3, an der dieses Farbpartikel unmittelbar benötigt wird.Grid jacket 20 applied in all details. As a result, each ink-guiding cup of the grid jacket 20 guides an ink particle via the inking roller 4 to a location on the printing form 3 where this ink particle is required immediately.

Anstelle einer Tiefdruckwechselplatte als Rastermantel kann auch, vgl. Fig. 6, eine Siebdruckplatte als Rastermantel 21 Verwendung finden. In dieser sind Näpfchen 22 vorgesehen, die durch die gesamte Dicke der Siebdruckplatte hindurchgehen. Der Boden dieser Näpfchen 22 wird durch die Oberfläche der Rasterwalze 5 gebildet.Instead of a gravure changing plate as a grid jacket, cf. Fig. 6, a screen printing plate can be used as a grid jacket 21. In this cups 22 are provided, which go through the entire thickness of the screen printing plate. The bottom of these cups 22 is formed by the surface of the anilox roller 5.

Wie Fig. 7 zeigt, ist die Anwendung des erfindungsgemäßen Verfahrens nicht auf Offsetdruckwerke beschränkt. Bei dem Druckwerk gemäß Fig. 7 ist ein Formzylinder 23 vorgesehen, der mit harten Hochdruckplatten 24 belegbar ist. Dem Formzylinder 23 wird dabei die Farbe wiederum mittels einer Auftragwalze 25 mit einer nachgiebigen, farbannehmenden Oberfläche zugeführt. Die Auftragwalze 25 steht in Kontakt mit einer Rasterwalze 26, auf die ein Rastermantel 27 aufgebracht ist, der lediglich in den druckenden Bereichen mit Näpfchen versehen ist. Der Rastermantel 27 ist als auswechselbare Hülse ausgebildet. Zur Farbzufuhr ist eine Kammerrakel 28 vorgesehen. Zur Farbzufuhr ist aber auch jedes andere bekannte Rakelfarbwerk einsetzbar. In betriebsbereitem Zustand weisen der Formzylinder 23, die Rasterwalze 26 und die Auftragwalze 25 gleiche Durchmesser auf und werden mit gleicher Drehzahl angetrieben.As FIG. 7 shows, the application of the method according to the invention is not restricted to offset printing units. In the printing unit according to FIG. 7, a forme cylinder 23 is provided which can be covered with hard high-pressure plates 24. The ink is in turn fed to the forme cylinder 23 by means of an applicator roller 25 with a resilient, ink-accepting surface. The application roller 25 is in contact with an anilox roller 26, to which a raster jacket 27 is applied, which is provided with cells only in the printing areas. The grid jacket 27 is designed as an exchangeable sleeve. A chambered doctor blade 28 is provided for ink supply. Any other known doctor blade inking unit can also be used for the ink supply. In the operational state, the forme cylinder 23, the anilox roller 26 and the applicator roller 25 have the same diameter and are driven at the same speed.

Auch bei dieser Ausführungsform wird der Rastermantel 27 mit einer Näpfchenkonfiguration hergestellt, die entweder nur bereichsweise oder genau auf den Farbbedarf der Hochdruckform 24 abgestellt ist. Anschließend werden Druckform und Rastermantel auf den Formzylinder 23 bzw. die Rasterwalze 26 aufgespannt.In this embodiment, too, the grid jacket 27 is produced with a well configuration that is either only partially or precisely tailored to the color requirements of the high-pressure mold 24. The printing form and screen jacket are then clamped onto the forme cylinder 23 or the screen roller 26.

Das erfindungsgemäße Verfahren ist auch bei Flexodruckwerken anwendbar. Hier werden die Druckform und der Rastermantel auf den Formzylinder bzw. die damit unmittelbar in Kontakt stehende Rasterwalze aufgebracht.The method according to the invention can also be used in flexographic printing units. Here the printing form and the screen jacket are applied to the forme cylinder or the screen roller that is in direct contact with it.

Der wesentliche Vorteil der Erfindung ist darin zu sehen, daß ohne zusätzliche Stell- oder Steuermittel eine beliebig genaue Anpassung der von der Rasterwalze weitergeführten Farbe an den Farbbedarf des Formzylinders und zwar sowohl im Umfangs- als auch in Seitenrichtung erfolgen kann. Da die Näpfchen des Rastermantels in unterschiedlicher Tiefe hergestellt werden können, kann hierdurch eine Anpassung an die jeweils zu verwendende Farbe erfolgen.The main advantage of the invention can be seen in the fact that any additional adjustment or control means can be used to adapt the color conveyed by the anilox roller to the ink requirement of the forme cylinder, both in the circumferential and in the lateral direction. Since the cups of the grid jacket can be produced in different depths, this can be adapted to the color to be used in each case.
